 AB9558'DESCRIBED BY NATIONAL GEODETIC SURVEY 1996 (AJL)
 AB9558'THE STATION IS LOCATED IN THE COUNTRY OF ANTIGUA, AT THE V C BIRD
 AB9558'INTERNATIONAL AIRPORT, SET INTO THE PARALLEL TAXIWAY FOR RUNWAY 10
 AB9558'(NOW CLOSED) AND EAST OF THE JUNCTION WITH RUNWAY 07/25.
 AB9558'OWNERSHIP--COUNTRY OF ANTIGUA AND BARBUDA, V C BIRD INTERNATIONAL
 AB9558'AIRPORT, PO BOX 1051, ST JOHNS, ANTIGUA.  AERODROME SUPERINTENDENT IS
 AB9558'MR ERROLL GEORGE.  AIRPORT CONTACT IS CHIEF OF AIR TRAFFIC SERVICES,
 AB9558'MR ANTHONY MEADE, PHONE (809) 462-0358, FAX (809) 462-0642.  THIS IS A
 AB9558'CONTROLED AIRPORT, PERMISSION TO ENTER THE AIRPORT COMPOUND IS
 AB9558'REQUIRED.  NOTE--AIRCRAFT TRAFFIC IS VERY HEAVY IN THE AFTERNOON.  TO
 AB9558'REACH THE STATION FROM THE SOUTHEAST SIDE OF THE TERMINAL BUILDING GO
 AB9558'NORTHEAST ON THE APRON, THEN ON A TAXIWAY FOR 0.25 MI (0.40 KM) TO THE
 AB9558'OLD RUNWAY 10 (NOW CLOSED) , BEAR RIGHT AND GO EAST ON THE OLD RUNWAY
 AB9558'FOR 0.30 MI (0.48 KM) CROSSING RUNWAY 07/25 TO A DIM TRACK ROAD ON THE
 AB9558'LEFT AT THE PAPI LIGHTS, TURN LEFT AND GO NORTHEAST ON THE DIM TRACK
 AB9558'ROAD FOR 0.05 MI (0.08 KM) TO THE OLD PARALLEL TAXIWAY FOR RUNWAY 10
 AB9558'AND THE STATION SET INTO THE CONCRETE TAXIWAY ON THE RIGHT.  THE
 AB9558'STATION IS 281.7 FT (85.9 M) EAST OF A RUNWAY LIGHT AT THE
 AB9558'INTERSECTION OF THE TAXIWAY AND RUNWAY 07/25, 16.0 FT (4.9 M) SOUTH OF
 AB9558'THE TAXIWAY CENTER AND 9.0 FT (2.7 M) NORTH OF THE SOUTH EDGE OF THE
 AB9558'TAXIWAY.  THIS IS A SECONDARY AIRPORT CONTROL STATION. NOTE--AT THIS
 AB9558'TIME THE LINE OF SITE BETWEEN THIS STATION AND THE PAC IS OBSTRUCTED
 AB9558'BY BRUSH BUT SHOULD BE CLEARED BY AIRPORT PESONNEL IN THE NEAR FUTURE.

 AB9238.No vertical observational check was made to the station.
 AB9238
 AB9238.The X, Y, and Z were computed from the position and the ellipsoidal ht.
 AB9238
 AB9238.The Laplace correction was computed from DEFLEC99 derived deflections.
 AB9238
 AB9238.The ellipsoidal height was determined by GPS observations
 AB9238.and is referenced to NAD 83.
